Fold the two-stage reasonAct/observe pipeline into one bounded reason-act loop: each iteration is a single model call that either requests tools (results fed back as context) or answers directly — a tool-free response IS the final answer, so no separate observe stage is needed to decide when to stop. The last iteration drops tools and forces a final answer so the loop always terminates. - Remove the orchestrator/state/step/runLoop scaffolding and the fallback handler package; drive the loop directly from run(). - Flatten AgentSpec to a single prompt_file; derive the tool-less answer prompt from the same system prompt plus an answer directive. - Drop the agentObserve.txt prompt; keep agentReasonAct.txt. - Update agent.schema.json, config loader test, e2e test and fixtures to the flat single-stage config.

What
Collapse the two-stage
reasonAct/observeReAct pipeline into one bounded reason-act loop.Each iteration is a single model call that either requests tools (whose results are fed back as context for the next iteration) or answers directly — a tool-free response is the final answer, so no separate
observereasoning step is needed to decide when to stop. The last allowed iteration drops the tools and forces a final answer, so the loop always terminates with a real reply rather than exhausting its budget in silence.Changes
